CAR-CDUPLING.

SPECIFICATION forming part of Letters Patent No. 731 ,520, dated June 23, 1903. Application filed December 23, 1901. Serial No. 86,950. (No model.)

To all whom it may concern.-

Beit known that We,JAOOB E.STUBBLEBINE and J OHN H. STUBBLEBINE, citizens of the United States, residing at Plymouth, in the county of Luzerue and State of Pennsylvania, have invented certain new and useful Improvements in Oar-Couplers, of which the following is a specification.

This invention relates to coupling devices for railway-cars, and has for its object to pro-' vide a coupling device of such character that if a draw-head or attachment on either car becomes detached from the bottom of the car or broken in any way it will be carried along with the other car and not drop upon the track, and thus cause wrecks, &c.

The invention will first be described in the specification and then particularly pointed out in the claim at the end of the description.

Referring to the accompanying drawings, in which similar letters of reference are used to denote similar parts in each of the several views, Figure 1 is a detail sectional view of the draw-heads, coupling-link, and pins; and Fig. 2 is a detail sectional view.

In the drawings the draw-bars A comprise a head a' and a stem or yoke a. The drawhead w is provided with the usual longitudinal openings at, flared at its outer end for the reception of a coupling-link. In the instance shown this draw-head has the usual vertical cylindrical pin-socket a and a rectangular socket a within the latter of which sockets is seated a correspondingly-shaped pin or gate of, provided at one edge with a groove or channel a, to receive a stop-bolt a, passing horizontally through the side of the draw-head. The purpose of this construction is to'prevent the rectangular pin or gated" from jumping from its socket a under conditions likely to impart violent vertical movement to the pin or gate.

The coupling pin or bar D consists of a metal bar, rectangular in cross-section, having tapered ends, and at points at the terminals of the tapered surfaces transverse notches d to receive the lower ends of the gate a, as best shown in Fig. 1. These gates occupy normally the position shown at the left hand of Fig. 1that is to say, a position to engage the transverse notch d of the coupling-bar Dand their lower ends being beveled to accord with the tapered ends of the coupling-bar D, the object being that upon coupling cars fitted with our improvements the coupling-bar being in position on one car will automatically raise the coupling pin or gate on the adjacent car until the notch d of the bar D passes beneath the lower end of the coupling pin or gate, when the latter will fall, thus effecting the coupling of two adjacent cars.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is

In combination with a draw-bar, a coupling-bar tapered at its ends and provided at the inner terminals of its tapered surfaces with transverse notches having opposing vertical walls, and a coupling pin or gate loosely seated in a vertical slot in the draw-bar with its lower beveled end normally in position to engage the transverse slot of a coupling-bar, and a spring-pressed stop-bolt seated in one side of the draw-head and engaging a slot in the coupling-pin to prevent the removal of said pin.

In testimony whereof we aflix our signaturesin presence of two witnesses.
